你可能很容易记得今天上班时把汽车停在何处,但你可能不记得上星期二把汽车停在何处。同样,你可能记得昨晚晚餐吃过什么食物,但你可能不记得上星期的这个晚餐吃过什么食物。并非所有的记忆都这样脆弱。如果上星期一辆汽车撞上你的车,那你一定记得汽车停在哪儿。另外,你也记得在很久以前的一次宴会上,你吃过的食物。因为那些食物使你上吐下泻。实际上,我们许多人时常要避免那些曾经致病的食物。 You may easily remember where to park your car today, but you probably do not remember where to park your car last Tuesday. Again, you may remember what food was eaten last night, but you may not remember what was eaten last week at this dinner. Not all memories are so fragile. If a car hits your car last week, you must remember where the car stopped. In addition, you remember the food you had eaten at a long time ago. Because those foods make you vomit and diarrhea. In fact, many of us often avoid food that has become ill.
